Yes, when uploading your project, simply add a Project Brief (found in Step 5 of our Wizard), asking for the format you need (.srt, etc.).
Please remember that if you need the subtitles in the same language as your audio/video content, you should choose our Transcription service in the Wizard. - This option is available when you are logged in to your account on the site.
If the translator has to add a timestamp to create subtitles, there will be an additional charge of $0.5 per minute.
Please contact our support team for advice.
